A few explanations about the common sense of the pump head of the plastic packaging bottle for daily chemical products

Update:08-10-2021
⒈The raw materials of plastic bottles are usually PP, PE, K material, AS, ABS, acrylic, PET, etc.

⒉Cream bottles, bottle caps, stoppers, gaskets, pump heads, and dust covers are usually used for cosmetics with thicker walls. Injection molding; PET blow molding is two-step molding, tube embryo is injection molding, and the product packaging is Bottle blowing. Others, such as lotion bottles and scrubbing bottles with thin container walls, are blown bottles.

⒊PET materials are environmentally friendly materials, with high insulation, light weight, non-breaking characteristics, chemical resistance, strong transparency, can be made into pearlescent, colored, magnetic white, transparent, and widely used in gel water. The bottle mouth is usually the standard 16#, 18#, 22#, 24# caliber, which can be used with a pump head.

⒋Acrylic raw materials are injection-molded bottles, which have poor chemical resistance, and usually cannot be directly filled with paste. It needs to be isolated with an inner tank. The filling is not easy to be too full. Avoid the paste entering between the inner tank and the acrylic bottle. If cracks occur, the need for side-by-side packaging is higher because of scratches, which look particularly noticeable, with high permeability, and the sensory upper wall is extraordinarily thick, but the quotation is moderately expensive.

⒌AS, ABS: AS has better transparency than ABS, and has better durability.

⒍Mould development costs: blow moulds are 1,500 yuan to 4,000 yuan, injection molds are 8,000 yuan to 20,000 yuan. The materials of stainless steel molds are more expensive than those of alloy materials, but after use, several molds are produced at a time. The demand for output, if the output is large, you can choose a mold with four or six molds, and the customer can decide by himself.

⒎The order quantity is usually 30,000 to 10,000, and the color can be customized. It is usually made of primary color frosted and magnetic white, or added pearl powder. Although the bottle and cap are matched with the same color master, sometimes it is used for the bottle and cap. The raw materials are different, and the colors displayed are somewhat different.

⒏Silk printing has common inks and UV inks. UV inks have good effects, gloss and three-dimensional effect. The color should be recognized first when making a plate. The effect of silk screen printing with different raw materials will be different.

⒐The processing technology of bronzing and silver bronzing is different from that of gold powder and silver powder. The hard material and lubricating surface are more suitable for bronzing and silver bronzing. The soft surface is not good enough for bronzing and easy to fall. The gloss of bronzing silver Degree is better than printing gold and silver.

⒑The silk screen film should produce negative films, the graphic effect should be black, the background color should be bright, the hot stamping and silver hot technology should produce positive films, the graphic effect should be bright, and the background color should be black. The share of text and pictures should not be too small or too fine, otherwise the printing will not be effective.

⒒Bottle caps are usually equipped with inner gaskets, pull caps, and inner plugs. Very few are equipped with small spoons or droppers. This is mainly because of its sealing and ease of use.

⒓The production cycle is relatively moderate, about 15 days. The silk-printed cylindrical bottle is calculated in a single color, and the flat bottle or a special-shaped bottle is calculated in two colors or multiple colors.
